It’s more complicated than that. It’s called USB restricted mode. The lightning port is always willing to do a minimal subset of the protocols that it supports in order to do smart charging. By default most of the protocols it supports are disabled in BFU state. In AFU state it gets more complex than that. Accessories that you’ve previously connected can connect for one hour after the device is locked. This helps keep USB restricted mode from being really annoying if you briefly disconnect and reconnect an accessory.

USB restricted mode can be disabled by a user option (Settings > [Touch / Face] ID & Passcode > Allow Access When Locked > Accessories) or by a configuration profile. Disabling it allows accessories to connect at any time, and generally lowers the security of your device. But in some cases that’s necessary, for instance when you use an accessibility accessory to use your device.

If USB restricted mode is a concern for you, you should consider Lockdown Mode (Settings > Privacy & Security > Lockdown Mode). This changes several settings on your device to make it much more resilient to attack.

It’s not that simple. iOS has a really sophisticated system for deciding which things to keep in memory and which to evict, and it only does that when it needs more resources. Choosing which apps to kill is based on how recently an app was used, how much of share resources are in use, how often the app gets used, if it’s doing background processing, and other more subtle signals.

Usually if people notice apps being killed when in the background a lot it’s because one of the apps they’re switching to is using a lot of resources, which forces the eviction of other apps.

When you first boot up a device, most data on that device is encrypted. This is the Before First Unlock (BFU) state. In order to access any of that data, someone must enter the passcode. The Secure Enclave uses it to recreate the decryption keys that allow the device to access that encrypted data. Biometrics like Face ID and Touch ID won’t work: they can’t be used to recreate the encryption keys.

Once you unlock the device by entering the passcode the device generates the encryption keys and uses them to access the data. It keeps those keys in memory. If it didn’t, you’d have to enter your passcode over and over again in order to keep using your device. This is After First Unlock (AFU) state.

When you’re in AFU state and you lock your device, it doesn’t throw away the encryption keys. It just doesn’t permit you to access your device. This is when you can use biometrics to unlock it.

In some jurisdictions a judge can legally force someone to enter biometrics, but can’t force them give up their passcode. This legal distinction in the USA is that giving a passcode is “testimonial” because it requires giving over the contents of your mind, and forcing suspects to do that is not legal in the USA. Biometrics aren’t testimonial, and so someone can be forced to use them, similar to how arrested people are forced to give fingerprints.

Of course, in practical terms this is a meaningless distinction because both biometrics and a passcode can grant access to nearly all data on a device. So one interesting thing about BFU vs AFU is that BFU makes this legal hair-splitting moot: biometrics don’t work in BFU state.

But that’s not what the 404 Media articles are about. It’s more about the forensic tools that can sometimes extract data even from a locked device. A device in AFU state has lots of opportunities for attack compared to BFU. The encryption keys exist, some data is already decrypted in memory, the lightning port is active, it will connect to Wi-Fi networks, and so on. This constitutes a lot of attack surface that hackers could potentially exploit to pull data off the device. In BFU state, there’s very little data available and almost no attack surface. Automatically returning a device to BFU state improves resistance to hacking.

When playing survival or hardcore what’s the best items to include in bundles? The only item that comes to mind is logs for early and mid game. Maybe if I’m exploring and want to tame some things I can bring some feed items (bones, fish, seeds, hay) and some leads?

What do you mean in the near future? It already exists, https://welldeserved.me/. Watch the reveal video.

Also delete your expired certificate if you have one (for example after a year)

This is likely a bad mistake. Keep the old cert around.

There’s two possibilities:

The first possibility is that Actalis uses the same key pair for the new cert. This is not a great approach because it doesn’t defend against a leaked key or key overuse. After all, if the key can be trusted longer than a year, the first cert they issued should be valid for longer.

The second, and much worse possibility, is that renewing the cert gets a different private key. This can case data loss. Deleting the old identity means you lose the ability to decrypt any messages that were encrypted using that key! Even if your mail client stores the previously encrypted emails in decrypted form, you may receive a new email from a sender who does not yet have your new cert.

Actalis sends you your private key. This means they have access to your private key, and theoretically could use it to sign and decrypt your emails. A more secure but somewhat more complex system would use a certificate signing request (CSR) instead. In that case, you are the only person who ever has your private key, so only you can sign or decrypt your email.

Releasing the app on the same day to the Apple App Store and Apple Arcade is a nice win for Apple Arcade.
